Sonoma County Trails Challenge!

Trails Challenge 2017The Sonoma County Trails Challenge is an invitation to explore the Regional Parks and do something good for your body and mind! 

The Trails Challenge runs from June through September, when participants are invited to hike, run, bike or ride at least 5 trails featured in the free Trails Challenge guidebook. The guidebook includes park notes, trail ratings, turn-by-turn directions, maps, and suggestions for themed hikes, including an all-park challenge of more than 50 miles. 

When you finish, you'll get a free Trails Challenge gift and also could win park memberships and trail gear from REI for sharing your #TrailsChallenge photos.

The 2018 guidebook will be published in late May. In the meantime, you're invited to download the 2017 guide and keep it as a resource for exploring the parks.   

Happy Hiking!
